چکیده: Abstract: Today, for environmental and economic reasons, the use of renewable resources in photovoltaic networks has increased. The reduction of inertia and the uncertain state of electric energy production have caused problems such as the lack of balance in production and consumption and frequency control in solar networks.Therefore, the need for power storage has increased, for this purpose, the potential of photovoltaic power plants has been used. In this research, in order to adjust the network frequency and control the power reserve, the decreasing current power tracking algorithm has been used. Unlike the previous methods, this method does not need to estimate the maximum power in real environmental conditions. It does not require a radiation sensor or complex mathematical model estimation.The minimum power-current curve is obtained by using the maximum power-current curve, which is a simple linear function and can be obtained by fitting the curve to the line.Power storage control is investigated through simulation under constant and variable environmental conditions.The results show that the proposed control strategy is reliable, fast and accurate, and its effectiveness is effective in frequency regulation. Also, the photovoltaic system improves the frequency response of the system under conditions of sudden increase, sudden decrease and random change of load and production.The results have shown that the proposed frequency tuning strategy improves the frequency response characteristics of the system
